IMPROVEMENT IN CARRIAGE-THILL ATTACHMENTS.

Specification formingpart of Letters Patent No. 27,110, dated February14, 1860.

To all whom it may concern:

Be it known that I, HENRY E. CLINTON, of

V the town of \Voodbridge, county of New Haven, and State ofConnecticut, have invented a new and Improved Mode of CouplingCarriage-Shafts to the Shaft-Jack; and I do hereby declare that thefollowing is a full and exact description.

The nature of my invention consists in constructing the shaft-eye so asto hook onto the jack-bolt, and is secured in its place by means of aspring-key, thus doing away with the nut and screw which are now in use.

To enable others skilled in the artto make and use my invention, I willproceed to describe its construction and operation, and reference ismade to the accompanying drawings, and letters marked thereon, as partof this specification.

I construct the shaft-jack A of iron or steel, and leave the slot II ofsufficient Width to admit the shaft-eye C. I weld the jack-bolt or pivotE firmly in its place, as shown at E E, Figure 4, and leave space enoughbetween the bolt and the back of the slot to admit the shaft-eye C, andalso the spring-key B. The shaft-jack is attached to the axle-tree G byany of the known ways. The shaft F, I construct in the usual modes, andmake the shaft-eye C in the form of a hook, so as to clasp the jack-boltE, as shown at C C, Fig. 2. I make the key B of any suitable materialwith a head, and curve the side of the key which rests against theshaft-eye, so as to conform to the turn or curve of the shaft-eye, asshown at I, Figs. 2 and 3. I then cut the slot'J for the spring D to actin, as shown at Fig. 2. I attach the spring to the back of the key, asshown at K, Fig. 5. This spring is turned outward at right angles, so asto form a shoulder which rests again st the under side of the jack andprevents the key from getting out of place, as shown at L, Fig. 2. Thelower end of the spring is turned inward toward the slot. I couple theshaft to the jackbolt by removing the spring-keys and adj usting theshaft-eyes to the jack-bolts. The keys are then forced into the slotsand hold the shafts firmly in place. I detach or uncouple the shaft byremoving the spring-keys.

What I claim as my invention, and desire to secureby Letters Patent, is-

The application of the spring-key 13, substan tially and for thepurposes as is herein set forth.

HENRY E. CLINTON.
